Altitude Temperature (& Humidity) Chamber
MZ Series

Overview

The Altitude Chamber models enable environmental testing of electrical devices under both operational and storage conditions at high altitudes by controlling pressure, temperature, and humidity. They can simulate of altitudes of up to 45,000 meters (approx. 147,000 feet).
It allows verification of malfunctions in EVs and HVs operating under low-pressure, low-temperature, high-altitude conditions, as well as validation of quality and operation under aircraft cabin environments.

Complied with aircraft component test standards.
